[Qemu-devel] [PATCH 00/23] Remove cpu_get_physical_page_desc()

[Avi Kivity <avi@redhat.com>]

cpu_get_physical_page_desc() exposes the internals of the memory core to
callers; as such it prevents the refactoring planned there.  This patchset
converts all callers memory API equivalents and removes the function.

The conversion leaves a lot of potential for further cleanups; the
MemoryListener API (which replaces CPUPhysMemoryClient) guarantees matched
range_add and range_del calls, so the need to handle splitting is removed.
This is left for later.

Please review and test, especially the vhost and Xen parts, which I only
build tested.

Avi Kivity (23):
  memory: introduce memory_region_find()
  sysbus: add sysbus_address_space()
  memory: add memory_region_is_ram()
  framebuffer: drop use of cpu_get_physical_page_desc()
  memory: add memory_region_is_rom()
  loader: remove calls to cpu_get_physical_page_desc()
  framebuffer: drop use of cpu_physical_sync_dirty_bitmap()
  memory: replace cpu_physical_sync_dirty_bitmap() with a memory API
  memory: add API for observing updates to the physical memory map
  memory: add memory_region_is_logging()
  kvm: switch kvm slots to use host virtual address instead of
    ram_addr_t
  fixup: listener fixes
  kvm: convert to MemoryListener API
  vhost: convert to MemoryListener API
  xen, vga: add API for registering the framebuffer
  memory: temporarily add memory_region_get_ram_addr()
  xen: convert to MemoryListener API
  memory: remove CPUPhysMemoryClient
  kvm: avoid cpu_get_physical_page_desc()
  vhost: avoid cpu_get_physical_page_desc()
  virtio-balloon: avoid cpu_get_physical_page_desc()
  sparc: avoid cpu_get_physical_page_desc()
  Remove cpu_get_physical_page_desc()
